Nora Lighting NIOC-4RSLA 4" Iolite Can-less Adjustable Slot Trim
Couldn't load pickup availability
For homes and commercial spaces alike, the Nora NIOC-4RSLA gives clean recessed ceiling light with nothing hanging down.
Typical spots: kitchens, living rooms, hallways, bathrooms, offices and retail ceilings. With a damp rating it also suits bathrooms and covered patios. Because the fixture sits flush or out of sight, it works in Modern, Transitional and Scandinavian rooms alike; the finish you pick decides how much it shows.
Where it works
- Residential remodels and new builds, plus offices, shops and hospitality spaces.
Planning tip
Match the trim size to the housing size, then choose the look: open reflectors for general light, baffles to cut glare, lensed trims over showers. (our advice)
